Have to create files named

main.cpp
GPA.h
GPAlist.cpp
GPAlist.h
File.cpp
File.h
UI.h
UI.cpp

Among these files the main.cpp and the GPA.h files are given and there is a data file named student.csv which contains data for the output

 

The codes for the main.cpp file is as below.

main.cpp

 

#include
#include "GPAlist.h"
int main() {
if(gpaQuery("std.csv")) {
std::cout << "This should have failed!" << std::endl;
} else {
std::cout << "failed!, this is the correct exectution" << std::endl;
}
if(!gpaQuery("students.csv")) {
std::cout << "This should have worked, fix the problem!" << std::endl;
}
std::cout << "Goodbye!" << std::endl;
return 0;
}
The code for the GPA.h file is

#ifndef SDDS_GPA_H
#define SDDS_GPA_H
struct GPA {
char name[116];
double gpa;
int stno;
};
#endif // !SDDS_GPA_H

A comma-separated file of student records and their GPA (maximum of 100 records) with the following format:
Student Name, Student number, GPA

Sample:

Abraham Simpson,324543,3.9
Agnes Skinner,470546,4.0
Akira Kurosawa,411928,2.1  
Alice Glick,459608,3.3
A header file has a structure for the GPA record of a student under the name "GPA.h".

Have to write a command line program that receives an operation and a GPA value and performs the following queries on the records of the data file.

command line format:

? [operation][GPA Value]
Examples:

? <3.6 [ENTER]  list all the GPA records less than 3.6
? >3.9 [ENTER]  list all the GPA records more than 3.9
? ~3.0 [ENTER]  list all values close to 3.0 with 0.05 precision (between 2.95 and 3.05)
? !  End query
Your program should work under a function called gpaQuery.

gpaQuery

bool gpaQuery(const char* filename);

This function returns false if the filename can not be opened for reading, otherwise, it will return true.

gpaQuery runs as follows:

Data entry:

@2.2
~3.7
~3.8
<2.0
>3.8
~3.9
!
V1.1

sort the output based on student number (stno) in ascending order instead of GPA

Using the above data The function should work as follows:


Enter GPA query...
? @2.2
Syntax error: ? [Op][value]
Op: [>,<,~,!]
value: GPA value

Modules

Implement your program in three modules:

GPAlist: (must contain the gpaQuery function)
File: hold file-related functions
UI: holding User interaction functions.
